560TI SLI should net you about 20% more FPS depending on your resolution.
Though some people experience microstutter and other small issue when using multiple cards, I have never had that issue. I think going 560 SLI if you have the PSU for it and the Board for it is a good investment.

I would rather believe and find god doesn't exist than to not believe and find that he does.

The 560Ti SLI will give better fps, but if you want to upgrade later you will need to replace both (with the 580 you could jst add another). And 1gb vram can be a limiting factor for some games/resolutions. In the end its personal preference for the pros and cons.

If he stays at 1920X1200 he should be just fine, but you are right. Should he want to upgrade its going to be both cards and if he games on a bigger monitor 27"/30" there won't be enough V-Ram to do it.

cost is always a factor with me as is with many people,I ended up walking out with another 560ti and I am glad I did really happy with the results and I have had no micro stutter in any games(I"m running BF3 on Ultra) and getting decent frames single and multi player. Set up was a breeze and it works which always makes me happy.

You already had a 560Ti, which makes it an easy decision to just add another. He is building from scratch, so its a little different. Either way you won't be going wrong.
